Apple's "iTunes Movie Trailers" app is one hell of a misnomer: it doesn't just beam down the giant library of trailers we love. The new app lets you buy tickets, find nearby theaters, and chart film releases on a calendar.

This could be really, really useful: watch a trailer that looks great, check if it's out yet, find the nearest theater it's playing in, then buy a ticket for you and your beautiful significant other. Even sync it across your devices with iCloud! All from your iOS 5 gadget. Go download it now. [iTunes via 9to5Mac]
